N.A.M.F. is a term referring to absolutely terrible gamers who for some reason find their way on to Xbox Live and the Playstation Network and expect some type of respect from other high level players. NAMF in its simplest form means, n00b Ass Mother Fucker.

What the hell are you doing, you NAMF?? WE'RE BLUE AND THEY ARE RED! God, someone boot him please.
